Clear LiteRumble history

I have created my own LiteRumble instance running as a google app, as described in previous discussions. Now I want to know if it is possible to delete the battle history and the participated robots? I am experimenting with it since we want to have a roborumble event at our office and I want to delete my previous "testing" robots and matches and have a clean slate when we do the event.

You should be able to delete the data from the AppEngine web console. Otherwise you can simple make the clients upload to a different named rumble, and the old one can be for the demo/setup bots.

I have tried to remove the data from the datastore by selecting all database entries and delete them. But the data on the webpage is still there, so the data must be stored somewhere else. To create a new rumble seems like a annoying workaround :)
